Symmetry operations
Apply symmetry operations to a molecule and work out its point group.
Open the interactive simulation →How to use this simulation
- Choose a molecule.
- Choose an operation (Cn, σ, i, Sn) and drag the slider to watch it happen.
- If the molecule looks the same, record it as a symmetry element.
- Assign the point group and check it.
What to notice
- Ghost atoms show where each atom goes.
- Follow the flowchart: linear? high-order axes? highest Cn? perpendicular C₂? σh? σv?
